【Abstract】 In order to resolve a kind of question in substation automation about time, the theory of implement about nucleus event group in kernel is introduced firstly, and then the way of using nucleus event group is introduced secondly. A method based on nucleus event group is designed, which is the kernel task timer but not the application timer, so the question is resolved accurately and simply.更多还原
